图表作文(一)

第一节图表作文的类型

图表作文可分为两大类：表作文和图作文。

表作文

表格(Table)可以使大量数据系统化，便于阅读、比较。表格常由标题(Title)、表

头(Boxhead)(表格的第一行)、侧目(Stub)俵格左边的第一列)和主体(Body)部

分(表格的其余部分)等部分组成。如下表：

用表格表达的信息具体准确，而且表格中的各项均按一定规律排列。阅读表格时

要注意找出表格中各个项目的相互关系，表格中各个项目的变化规律。例如，上

面的表格中的数字说明，和1978年相比，1983年大学入学的人数在增加，而

小学的入学人数在减少。搞清楚这些变化规律也就读懂了表格的内容。

图作文

图作文又可分为三种：圆形图作文、曲线图作文和条状图作文。

(1)圆形图作文

圆形图(Piechart)也称为饼状图或圆面分割图。圆形图因为比较形象和直观，各

部分空间大小差别容易分辨，所以常用来表示总量和各分量之间的百分比关系。

整个圆表示总量，楔形块表示分量。有时圆形图还有数值表，两者结合可把各分

量表示得更准确、清楚。例如：

ThisisapiechartoftheaverageweeklyexpenditureofafamilyinGreat

Britain.Ascanbeseefromthechart,themainexpenditureofanaverage

Britishfamilyisspentonfood,whichaccountsfor25%ofitstotal

expenditure.Thenexttwosignificantexpendingitemsaretransportand

housing,whichare15%and12%respectively.Ifwetakeintoaccount

clothingandfootwear,whichmakesup10%,thefouressentialsoflifezthat

is,food,transport,housing,andclothingandfootwear,amountto62%of

thetotalexpenditure.

(2)曲线图作文

曲线图(Linegraph)也称为线性图或坐标图。曲线图最适合表示两个变量之间关

系的发展过程和趋势。一般来说，曲线所呈现的形状比某一点所代表的变量的值

更有意义。曲线图有横轴和纵轴。一般先看横轴所代表的数量或时间等，然后再

看纵轴所显示的意义。同时必须找出线条所反映的最高或最低的变化。例如：

这个曲线图的横轴代表1990年的不同的月份，纵轴代表交通事故的数量。从交

通事故曲线图上可知，前八个月的交通事故的数量有升有降。曲线图在八月份升

到了最高点(39),此后一直呈下降的趋势，十二月份降到了最低点(16)。可见,

1990年的交通事故的数量总体上呈下降的趋势。

(3)条形图作文

条形图(Bargraph)也称为立柱图或圆柱图。条形图由宽度相同但长度不同的条

块代表不同的量。当要比较几个项目或量时，常用不同颜色来区分。条形图主要

用来表示：1)同一项目在不同时间的量;2)同一时间不同项目的量。阅读条形图时,

要先看图例，再看横轴、纵横各代表什么量，每一个刻度所代表的值是多少，最

后找出图中各长条所表示的数据及各长条间的相互关系。例如：

左边的条形图的横轴代表时间，纵轴代表期望寿命(LifeExpectancy),这一

条形图想要体现的是同一项目(期望寿命)在不同时间的量。右边的条形图的横轴

也是代表时间，纵轴是代表婴儿的死亡率(InfantMortality)；这一条形图想要体

现的也是同一项目（婴儿的死亡率）在不同时间的量。左边的条形图表明1990年

的人均期望寿命比I960年的人均期望寿命长20岁，而1990年的婴儿死亡率

比1960年的婴儿死亡率下降了50%。

第二节图表作文的出题形式

例1题目：ChangesinPeople'sDiet

Studythefollowingtablecarefullyandyourcompositionmustbebased

ontheinformationgiveninthetable.Writethreeparagraphsto:

l.statethechangesinpeople*sdiet（饮食）inthepastfiveyears;

2.givepossiblereasonsforthechanges;

3.drawyourownconclusions.

Youshouldquoteasfewfiguresaspossible.

例2题目:CarAccidentsDeclininginWaltonCity

Rememberthatyourcompositionmustbewrittenaccordingtothe

followingoutline;

l.Riseandfalloftherateofcaraccidentsasindicatedbythegraph;

2.Possiblereason（s）forthedeclineofcaraccidentsinthecity;

3.Yourpredictionsofwhatwillhappenthisyear.

Yourcompositionshouldbenolessthan120wordsandyoushould

quoteasfewfiguresaspossible.

例3Forthispart,youareallowed30minutestowriteacompositionon

thetopicHealthGaininDevelopingCountries.Yourcompositionmustbe

nolessthan120wordsandyoushouldbaseyourcompositiononthe

followinginstructions(giveninChinese):

1.以下图为依据描述发展中国家的期望寿命(lifeexpectancy)和婴儿死亡率

(infantmortality)的变化情况

2.说明引起变化的各种原因

从以上例子可见，图表作文一般在题目中给出作文的标题和一个或几个统计表格、

圆形图、曲线图或条形图，有时还用英文或中文提纲的形式给出提示，要求我们：

1)用文字描述图表，客观解释图表中所传递的信息、，并找出某种规律或趋势；

2)就图表中所反映的某种趋势或问题分析其原因或后果。

第三节图表作文的写作要领

图表作文着重说明事实，常常是通过对图表中所反映的具体数据的说明、分析、

比较，对某种事物或现象的事实或变化情况等加以说明，并提出结论或看法。因

此，图表作文常常采用议论文体的写作方法。

写好图表作文，关键在于能否读懂图表中所提供的信息，把握各信息间的联系，

用准确流畅的语言把这T言息表达出来，并就这一B息发表自己的看法。

图表作文的写作步骤

写图表作文时，要注意遵循以下步骤：

1)认真分析图表的含义,弄清图表中所含的信息及不同信息间的关系；

2)确定文章的主题思想，构思出文章的基本框架，筛选出能说明图表主题思想的

典型数据；

3)编列文章的提纲;

4)根据文章的提纲，将各段的提纲内容扩展成段落，然后将各个段落组成文章,

注意段与段之间的衔接与过渡；

5)检查与修改。

图表作文的篇章结构

写图表作文时，常采用三段式的谋篇方式。文章的第一段往往分析图表中的数据

变化反映什么问题或趋势，概述图表所揭示的信息。第二段分析造成这一问题或

趋势的原因。第三段则展望未来的情况或提出解决问题的办法或建议。这一结构

可以简单地表述为：

第一段：概述图表反映的主题思想

第二段：分析产生的原因

第三段：展望未来或提出方法或建议

图表作文常用的句型

(1)常用的开篇句型(即概述图表内容时常用的表达法)

①Accordingtothetable/piechart/linegraph/bargraph,wecan
